How Many Watts Does A Battery Charger Use

Battery chargers have a primary purpose of giving energy to a rechargeable battery or a secondary cell by means of an electric current driven through the item. Battery chargers differ when it comes to functions and sizes. How many watts does a battery charger use, though? This article will discuss all you need to know about chargers and the functions it can do.

First, we are going to discuss the kinds of chargers commonly used. We have the simple charger, which is a type of charger that operates by providing a constant DC resource to the battery in order to generate a charge. We also have the trickle charger, which is a kind of charger that operates by giving a low current to replenish big and small batteries. Another is the timer charger, which stops the procedure after a preset period. Then we have the smart charger, which is utilized to get in touch with the battery’s state in order to adjust the charging process.

The simple charger is affordable and it generates a simple charge to batteries like AA ones. It takes longer for this type to charge items compared to other methods. The trickle kind, meanwhile, is utilized to charge small and big batteries used for vehicles, RVs, and boats. It is typically used to maintain batteries that require replenishment. A timer charger is a unit that is typically employed for charging Ni-Cd cells; however, it has hitches since it can lead to overcharging, thereby lessening the efficiency of the battery. The smart charger is considered to be the most effective since it is adjusted to terminate the charge of the item due to certain essential factors from time to voltage. Overcharging, therefore, is a rarity with smart chargers.

Watts Consumption of a Battery Charger

If you want to know how many watts a battery charger uses, you have to read the next part. Batteries all have an internal resistance. Whenever you charge your batteries, this resistance changes some of the energy during the charge into heat. For example, if you are charging a 10 voltage battery at a degree of 100 watts, it would need users to apply 10 voltage at 10 amps. However, if the battery has a 1-ohm resistance, users would require an 11-volt charger, which means users will have to provide 110 watts of power in order to acquire 100 watts to the battery.

The 10 watts that remain turns into wasted heat. In addition, there is also energy lost while discharging the battery. That is just the variable quantity, though. Draining the battery at a lower power for an extended period of time is more efficient compared to draining it fast at a higher rate of power. The chemical procedure that lets go of battery energy also takes place in a slow manner when not put in use, hence you also lose energy with a sitting battery. The efficiency of a battery charge depends on the design of the battery as well. Overcharging can do damage not only to the battery but the charger as well. As soon as the battery is charged completely, you will be acquiring no further efficiency in the energy you supplemented.

When looking for a charger, you have to first know your needs. Determine what battery size you want to use or plan to use and the manner in which you want them charged. Also, check your existing gadgets’ needs to best address your power needs in total. Crunch some numbers to determine the amount of wattage you would like to have on hand. There are lots of different chargers being sold in the market right now. There are portable models and powerful ones.

Now you know how many watts does a battery charger use. These chargers are made available by battery suppliers. You can look for a reputable supplier in your area by means of the internet. You can also ask friends and workmates where to find good ones—surely they can lead you to a seller who offers quality chargers. When you are buying a charger, look for a seller who retails chargers from different companies. This way, you will have the versatility to select from a broader range of products. There are also sellers and suppliers who allow customers to rent chargers for a limited time. Most suppliers also provide servicing and repairs so you won’t have to deal with maintenance or repairs yourself.
